No damage was reported Monday after an earthquake hit western Kentucky.

The temblor was felt throughout the region, including parts of southern and eastern Missouri, said John Minch, a geophysicist at the National Earthquake Center (search) in Golden, Colo.

The 3.9 magnitude quake hit at 7:21 a.m. CDT, Minch said. It was centered near Clinton in Hickman County, he said. In addition to western Kentucky and parts of Missouri, it was felt in southern Illinois and northwest Tennessee

"It moved the floor," said Marie Hart, a dispatcher for Kentucky State Police in Mayfield, near Clinton. "It was like standing on water."

Minch said he wasn't sure whether the quake originated from the New Madrid Fault (search), based in the Missouri Bootheel, which runs through western Kentucky.

Earlier this month, a 4.0 temblor was felt across northwest Tennessee and southwest Kentucky, but caused little damage.
